  document.querySelectorAll('a[href]').forEach(function (a) {
    var rel = (a.getAttribute('rel') || '').split(/\s+/).filter(Boolean);
    if (rel.indexOf('noreferrer') === -1) rel.push('noreferrer');
    if (rel.indexOf('noopener') === -1) rel.push('noopener');
    a.setAttribute('rel', rel.join(' '));
  });
})();
